		<h1>Language Class</h1>

		<p>The Language Class provides functions to retrieve language
			files and lines of text for purposes of internationalization.</p>

		<p>
			In your CodeIgniter system folder you'll find one called
			<dfn>language</dfn>
			containing sets of language files. You can create your own language
			files as needed in order to display error and other messages in other
			languages.
		</p>

		<p>
			Language files are typically stored in your
			<dfn>system/language</dfn>
			directory. Alternately you can create a folder called
			<kbd>language</kbd>
			inside your
			<kbd>application</kbd>
			folder and store them there. CodeIgniter will look first in your
			<dfn>application/language</dfn>
			directory. If the directory does not exist or the specified language
			is not located there CI will instead look in your global
			<dfn>system/language</dfn>
			folder.
		</p>

		<p class="important">
			<strong>Note:</strong>&nbsp; Each language should be stored in its
			own folder. For example, the English files are located at:
			<dfn>system/language/english</dfn>
		</p>



		<h2>Creating Language Files</h2>

		<p>
			Language files must be named with
			<kbd>_lang.php</kbd>
			as the file extension. For example, let's say you want to create a
			file containing error messages. You might name it:
			<kbd>error_lang.php</kbd>
		</p>

		<p>
			Within the file you will assign each line of text to an array called
			<var>$lang</var>
			with this prototype:
		</p>

		<code>$lang['language_key'] = "The actual message to be shown";</code>

		<p>
			<strong>Note:</strong> It's a good practice to use a common prefix
			for all messages in a given file to avoid collisions with similarly
			named items in other files. For example, if you are creating error
			messages you might prefix them with
			<var>error_</var>
		</p>

		<code>
			$lang['
			<var>error</var>
			_email_missing'] = "You must submit an email address";<br /> $lang['
			<var>error</var>
			_url_missing'] = "You must submit a URL";<br /> $lang['
			<var>error</var>
			_username_missing'] = "You must submit a username";
		</code>


		<h2>Loading A Language File</h2>

		<p>In order to fetch a line from a particular file you must load
			the file first. Loading a language file is done with the following
			code:</p>

		<code>
			$this->lang->load('
			<samp>filename</samp>
			', '
			<dfn>language</dfn>
			');
		</code>

		<p>
			Where
			<samp>filename</samp>
			is the name of the file you wish to load (without the file
			extension), and
			<dfn>language</dfn>
			is the language set containing it (ie, english). If the second
			parameter is missing, the default language set in your
			<kbd>application/config/config.php</kbd>
			file will be used.
		</p>


		<h2>Fetching a Line of Text</h2>

		<p>Once your desired language file is loaded you can access any
			line of text using this function:</p>

		<code>
			$this->lang->line('
			<samp>language_key</samp>
			');
		</code>

		<p>
			Where
			<samp>language_key</samp>
			is the array key corresponding to the line you wish to show.
		</p>

		<p>Note: This function simply returns the line. It does not echo
			it for you.</p>

		<h3>Using language lines as form labels</h3>

		<p class="important">
			This feature has been deprecated from the language library and moved
			to the
			<kbd>lang()</kbd>
			function of the <a href="../helpers/language_helper.html">Language
				helper</a>.
		</p>

		<h2>Auto-loading Languages</h2>
		<p>
			If you find that you need a particular language globally throughout
			your application, you can tell CodeIgniter to <a
				href="../general/autoloader.html">auto-load</a> it during system
			initialization. This is done by opening the
			application/config/autoload.php file and adding the language(s) to
			the autoload array.
